Post preserver



JOHN E. BITTING, OF LOS ANGELES, CALIFORNIA.

yPOST PRESERVER.

Specification'of Letters Patent. Patented Julie 6, 19220 v 'Application filed January i1, 1921. Serial-No. 436,436.

To all whom t may concern.' 'f

Be it known that I, JOHN E. Bi'rTING, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and Statefof California, have invented new and useful improvements in Post Preservers, of which the following is a specification.

It is the object of this invention to provide means for preserving wooden posts and the like, such as telegraph poles.

' rl`he invention provides a casing adapted to receive the vend of the post, which is inserted in the ground, and which is so arranged as to rigidly support the post while permitting the saturation of the end of the -post which is inserted in the ground with a suitable preservative.

The invention will be readily understood from the following description of the accompanying drawings, in which:

Figure l is a side elevation of a post having the improved preserving means employed in connection therewith, and shown in longitudinal section.

Figs. 2 and 3 are transverse sections on the lines 2 2 and 3--8 of Figure l.

The post in connection with which the preserving ineans is employed is shown at l, and may be a telegraph pole, fence post or the like. The lower end thereof, which is received in the ground, is tapered downwardly as shown at 2.

A casing 3, preferably, of metal is received over the tapering end 2 of the post, and said casing preferably tapers downwardly,l so that it may be readily inserted in the ground. At its lower end it is provided with an annular flange 4L for retaining the casing inposition when the earth E is packed around the same. Longitudinally extending ribs 5 arepreferably also provided on the outside of the casing for preventing turning of said casing in the earth.

The wall of casing 3 is radially spaced from the end 2 of the post received therein` and radial ribs 6, which are circumferentially spaced as shown at 7, extend inwardly from casing 3, so as to define a central downwardly tapering bore 8 into which the tapering end of the post is wedged.

The upper end of casing 3, preferably, extends above the surface of the earth, and terminates in an end cap 9, which is provided with an axially inwardly extending frame l() extending to the ends of ribs 6,

which preferably terminate short of the to-p of the casing. By this arrangement an annular space il is provided a't the top ofthe casing communicating with the spaces 7 between the ribs 6. n

After the casing has been positioned inthe ground, and the pole has been inserted therein, the latter is preferably sealed in position by providing a groove 12 around the axial bore provided in end plate 9, and lilling said groove with plastic material such as cement. A filling-plug 13 is provided in end. plate 9 by means of which a suitable preserving liquid, such as creosote, may be supplied to spaces 7 and 11.

The construction as thus described provides a rigid support for a post in casing 3 by the wedging engagement of the tapering end of the post in the tapering bore 8, and at the same time a preserving material is maintained in intimate vContact with the post, so as to prevent rotting of the latter. When the post is thus mounted in position within its casing, an airtight construction is also provided, which will prevent deterioration of the post from atmospheric influences.

Various changes may be lmade without departing from the spirit of the invention as claimed.

1What is claimed is: l

l. A preserving casinghaving inwardly extend-ing radial ribs forming an axial tapering bore, and an end plate on said casing having an axial inwardly extending flange extending to the ends of said ribs, the spaces between said ribs, and the space betweeny said flange and said casing communicating with the saine, being adapted to contain a preservative.

2. A preserving casing having inwardly extending radial ribs forming an axial tapering bore communicating with the spaces between' said ribs, and an end plate upon said casing having an axial inwardly extending flange forming a prolongation of said axial boie and extending to the ends of said ribs, the spaces between said ribs, and the spaces between said iiange and said casing, com

municating with the same, being adapted to contain a preservative.

3. A post preserving casing having inwardly extending radial ribs definingL an axial bore that is adapted to receive the lower portion of a post, the chambers between said ribs being adapted to receive a preservative, the top of said casing being provided with an end plate in which is formed a centrally arranged openingI` and there being a groove formed in the top of said plate and concentrieally arranged around the opening therein, which groove is adapted to receive a Y the upperend of said casing, which end plate le provided with a centrally arranged `openinoe a frame extending downwardly from ysaid end plate around the opening 15 therein, and there being a channel formed in the top of the `plate and disposed about the opening therein, which Channel `is adapted to receivel plastio lfnaterial.`

In testimony vvhereotl i have signed my 20 name to this specification. 1
